Abstract

The present paper employs supported ruthenium nanoparticles alongside catalytic quantities of the radical initiator, which are proven to be capable of cyclooctene oxidation with green conditions, in the absence of solvent, with air as the main oxidant and without sacrificial reductant. The paper examines the effects of a range of radical initiators and how the products are distributed over time. Furthermore, the paper addresses the reaction pathways to the epoxides and allylic alcohol, the latter being the primary by-product, whilst also analysing the impact of the technique of synthesis, reaction time, and various supports. Catalyst activity can be markedly improved by adopting a sol-immobilization technique to synthesise the catalysts, with retention of selectivity to the epoxide.
无溶剂条件下负载钌催化剂氧化环烯烃
本论文采用负载钌纳米颗粒和催化量的自由基引发剂,证明了在绿色条件下,在没有溶剂的情况下,以空气为主要氧化剂,不牺牲还原剂,能够氧化环烯。本文考察了一系列自由基引发剂的影响以及产物是如何随时间分布的。此外,本文还讨论了环氧化物和烯丙醇的反应途径,后者是主要的副产物,同时还分析了合成技术,反应时间和各种载体的影响。采用溶胶固定化技术合成催化剂可显著提高催化剂活性,并保留对环氧化物的选择性。
